The Nose Knows
Dogs have an incredible sense of smell, so they are often used in search and rescue operations, drug detection, and other similar roles. They can sniff various scents, from bombs and drugs to lost hikers and cancer.
But many people don’t realize that a dog’s sense of smell is closely tied to its emotions. They can detect and differentiate between various human emotions by how we smell. This explains why dogs can sense when their owner is upset or anxious and will often comfort them in their way.
